Methods and systems for camera drift correction

A system for video frame alignment comprising:

• a video acquisition module configured to collect image data comprising at least two image frames;
• a processor;
• and
• a computer-usable medium embodying computer code, said computer-usable medium being coupled to said processor, said computer code comprising non-transitory instruction media executable by said processor configured for:
• extracting a line profile along at least one line path in each of said at least two video frames;
• selecting one of said at least two video frames as a reference video frame;
• aligning at least one of said at least one line profiles with said line profile in said reference video frame;
• translating each of said at least two video frames according to said corresponding line profile alignments;
• and
• removing a camera shift from said at least two video frames according to said translation and alignment of said at least one of said at least one line profiles with said line profile in said reference video frame.

• a line profile extraction module which extracts a line profile along at least one line path in each of said at least two video frames;
• a reference frame selection module which selects one of said at least two video frames as a reference video frame;
• a registration module which aligns at least one of said at least one line profiles with said line profile in said reference video frame;
• and
• a correction module for translating each of said at least two video frames according to said corresponding line profile alignments to thereby remove a camera shift from said at least two video frames according to said translation and alignment of said at least one of said at least one line profiles with said line profile in said reference video frame.
